In 1589 Pope Sixtus V united to the Congregation of St Ambrose the monasteries of a group known as the " Brothers of the Apostles of the Poor Life " ( or " Apostolini " or " Brothers of St. Barnabas "), whose houses were in the province of Genoa and in the March of Ancona.

Pope Sixtus IV gave the nuns canonical status in 1474.

Pope Paul II suppressed this college ; but Sixtus IV ( Constitutio 16, " Divina ") reestablished it.

After the murder in that year of Henry III of France, Pope Sixtus V sent Enrico Caetani as legate to Paris to negotiate with the Catholic League of France, and chose Bellarmine to accompany him as theologian.

In 1589, by the bull Cum pro nostri temporali munere, Pope Sixtus V re-organised the choir of St Peter's, Rome specifically to include castrati.

Pope Sixtus V limited the number of cardinals to 70, composed of six cardinal bishops, 50 cardinal priests, and 14 cardinal deacons ; however, Pope John XXIII began to exceed the overall limit of 70, and this continued under his successors.

In 1587 Pope Sixtus V sought to arrest this growth by fixing the maximum size of the College at 70, including 50 cardinal priests, about twice the historical number.

Under the 1587 decree of Pope Sixtus V, which fixed the maximum size of the College of Cardinals, there were 14 cardinal deacons.

More likely, Pope Sixtus IV granted Cesare a release from the necessity of proving his birth in a papal bull of 1 October 1480.

Pope Sixtus IV is known for having built the Sistine Chapel, which is named for him.

" She is only a woman, only mistress of half an island ," marvelled Pope Sixtus V, " and yet she makes herself feared by Spain, by France, by the Empire, by all ".

The Spanish manuscript also contains a preface by one assuming the pseudonym ' Fra Marino ', claiming to have stolen a copy of the Italian version from the library of Pope Sixtus V. Fra Marino reports that, having a post in the Inquisition Court, he had come into possession of several works, which led him to believe that the Biblical text had been corrupted, and that genuine apostolic texts had been improperly excluded.

On 28 February 1476, Pope Sixtus IV, a Franciscan after whom the Sistine Chapel is named, authorized those dioceses that wished to introduce the feast to do so, and introduced it to his own diocese of Rome in 1477, with a specially composed Mass and Office of the feast.

In Rome, the papal collections were brought together by Pope Nicholas V, in separate Greek and Latin libraries, and housed by Pope Sixtus IV, who consigned the Bibliotheca Apostolica Vaticana to the care of his librarian, the humanist Bartolomeo Platina in February 1475.

In the 16th century Sixtus V bisected Bramante's Cortile del Belvedere with a cross-wing to house the Apostolic Library in suitable magnificence. The 16th and 17th centuries saw other privately endowed libraries assembled in Rome: the Vallicelliana, formed from the books of Saint Filippo Neri, with other distinguished libraries such as that of Cesare Baronio, the Biblioteca Angelica founded by the Augustinian Angelo Rocca, which was the only truly public library in Counter-Reformation Rome ; the Biblioteca Alessandrina with which Pope Alexander VII endowed the University of Rome ; the Biblioteca Casanatense of the Cardinal Girolamo Casanate ; and finally the Biblioteca Corsiniana founded by the bibliophile Clement XII Corsini and his nephew Cardinal Neri Corsini, still housed in Palazzo Corsini in via della Lungara. The Republic of Venice patronized the foundation of the Biblioteca Marciana, based on the library of Cardinal Basilios Bessarion. In Milan Cardinal Federico Borromeo founded the Biblioteca Ambrosiana.
